FE B A- ULRICH, E R E K, ILLI O LAND-FIARKER.

To all whom it may concern:

Be it known that I, PETER A. ULRICH, a citizen of the United States ofAmerica, residing at Deer Creek, in the county of Tazewell and State ofIllinois, have invented new and useful Improvements in Land-Markers, ofwhich the following is a specification.

This invention relates to markers or gages for corn planters and has forits objects to simplify and improve the construction and operation ofthis class of devices.

lVith these and other ends in View which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination ofpartswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawing,Figure 1 is a rear elevat-ion, showing a frame of a cornplanter equipped with the improved marking device. Fig. 2 is aperspective view, showing the operating mechanism of the improvedmarking device detached. Fig. 3 is a sectional detail view of a portionof the marker arm.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved marking device includes a rock shaft 5 supported foroscillation in suitable bearings upon one of the side members of aplanter frame, as shown in Fig. 1, or upon one of the arms of anL-shaped bracket, as shown in Fig. 2 of the drawings, where said bracketis shown at 6, said bracket being adapted to be bolted or otherwisesecured upon one of the rear corners of the planter frame A. It is to beunderstood that the improved device includes two markers designed forthe right and left hand corners of the frame, respectively. The rockshaft 5 is provided at its frontend with an arm 7 having a foot piece orpedal 8 extending laterally to a convenient position with reference tothe operator, whose seat 9 is supported in the usual manner upon theplanter frame. The pedal-carrying arm 7 is disposed at What will be forconvenience designated as Specification of Letters Patent.

Application filed December 28 1909.

Patented May 17, 1910.

Serial No. 535,282.

the inner end of the rock shaft 5, being the end distant from the sideof the planter frame; the outer end of the rockshaft has a tubularextension 10 forming an arm which is disposed radially with reference tothe rock shaft and approximately at right angles to the arm 7. Fittedadjustably in the tubular arm 10 is a rod 11 which is capable of beingsecured at various adjustments by means of a cotter pin 12 engaging anyone of a plurality of perforations 13 in the rod 11, said rod carryingat its outer end a gage wheel 14 which is mounted for rotation in anysuitable, convenient and well known manner.

An arm or lever 15, which is pivotally mounted upon the rear side of theplanter frame in a corresponding position upon the bracket 6, is guidedat its free end in an arcuate keeper l6 suitably supported upon theplanter frame or upon the side of the bracket 6. Pivotally supportedupon the arm or lever 15 is an L-shaped bracket 17, the outwardlyextending arm of which has an aperture 18 for the passage of an eye bolt19 which is connected with said pivoted bracket by means of a nut 20.The eyebolt 19 is connected by a tension spring 21 with a chain 22, oneof the links of which engages a hook 23 formed upon a clamp 2a which isadjustably mounted upon the tubular arm 10 by fastening means, such as abolt 25.

The operation and advantages of this invention will be readilyunderstood from the foregoing description taken in connection with thedrawings hereto annexed by those skilled in the art to which itappertains.

One of the markers is mounted upon the planter frame adjacent to eachside of said frame, the position being adjacent to the rear corners, andthe said marking devices are made right and left handed, as will be seenby reference to Fig. 1. In Fig. 1 the right hand marker has been shownin ground-engaging position, while the left hand marker has been shownraised to a non-operative position; in the former case the pivoted armor lever 15 is positioned adjacent to the lower end of the keeper 16,and the tension of the spring 21 is exerted to force the tubular armdownward, thus holding the gage wheel 14 in ground-engaging position, aswill be seen. The operator by placing his foot upon the pedal 8 andpressing downward will oscillate the rock shaft 5, thus bringing the arm10 to an elevated position, as indicated at the left hand side ofFig. 1. As the arm 10 ascends the spring 21 is strained until a point ispassed at which the pivotal point of the bracket 17, the fulcrum of thelever and the attaching point of the chain 22 to the hook 23 are inalinement with each other. This point having been passed, the tension ofthe spring will be exerted to swing the lever 15 in an upward directionand to hold the arm 10 with its related parts in an elevated position,as shown at the left hand side of Fig.

1. It is obvious that at each end of a row, when the machine is turned,the marker at one side will be raised from a ground-eugaging position toa non-operative position, and that after the machine has been turned,the marking device previously out of commission will be lowered and putinto active use.

The device, as will be seen, is simple in construction, and it iscapable of being conveniently installed at small expense upon the framesof corn planters of ordinary construction. It will also be seen thatadjustment may readily be made for the purpose of making the deviceapplicable to machines adapted for planting the corn at variousdistances apart.

Having thus described the invention what is claimed as new, is

1. In a device of the character described, a rock shaft having aradially extending marker-carrying arm, a lever fulcrumed adjacent tosaid rock shaft, an arcuate keeper constituting a-guide for said lever,and connecting means between said lever and the marker-carrying arm,said connecting means including a tension spring.

2. In a device of the character described, a rock shaft having aradially extending marker-carrying arm, a lever fulcrumed adjacent tothe rock shaft, a keeper constituting a guide for said lever, anL-shaped bracket pivoted upon the lever, and connecting means includinga tension spring between said L-shaped bracket and the marker-carryingarm.

3. In a device of the character described, a rock shaft having aradially extending marker-carrying arm, a lever fulcrumed adjacent toone end cf the rock shaft, a keeper constituting a guide for said lever,an L- shaped bracket pivoted upon the lever, an.

eye bolt connected adjustably with said bracket, a tension springconnected with the eye bolt, a clamp secured upon the markercarrying armand having a hook, and a chain connecting said hook with the tensionspring.

In testimony whereof I aflix my signature in presence of two witnesses.
